WILLIAM KOCH, OF NEW YORK, N. Y.

QUILTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,552,6lated December27, 1887.

Application filed December 26, 1885. Serial No. 186,681. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM KooH, of the city, county, and State of NewYork, have invented a certain new and useful Improvement inQuilting-Machines, of which I declare the following to be a full, clear,and exact description, reference being had to the accompanying drawings,forming a part thereof.

This invention is in the nature of an improvement in quilting-machines;and the invention consists in a quilting-machine with three or moreneedlebars constructed and combined so that the spaces between all orany two of the bars may be varied, as with greater particularity ishereinafter shown, described, and claimed.

Inthe accompanying sheet of drawings, Figure 1 represents across-section of the needlebars of my machine; Fig. 2, a plan or topview of same; Fig. 3, detail views of sleeves. Fig. 4 is also a planview of the needle-bars separated by sleeves of unequal lengths.

Similar letters of reference indicate like parts in the several figures.

This invention relates particularly to quilting-machines which havethree or more rows of needles fixed to a corresponding number ofneedle-bars, for the purpose of quilting designs of given patterns onthe fabrics exposed to the action of the needles. Now it is obvious thatif the several rows of needles are of character and design, withoutdeviation or va:

riation, and it is to break up and change this uniformity of design thatI construct my quilting-machine with its needle-bars A arranged parallelwith each other and connected by bolts 1). Now, as these bars have eachfixed to them needles 0, it is plain that the order, arrangement, ordesign of the stitches may be changed by increasing or decreasing thespace a between these needle-bars; and to that end, by the use ofsuitable nuts applied to the bolts 1) and removable sleeves B, ofdifferent lengths, which may be placed on the bolts 12 and between thebars A, as shown in Fig. 1, the spaces a between the bars may be made tovary throughout the series, so that, the relative position of the barsbeing altered, the designs stitched'by the needles will varyaccordingly, and an almost infinite variety of stitching or quilting beproduced by this simple adjustment of the needle-bars.

Of course many means may be adopted for effecting this adjustment, and Ido not therefore desire to confine myself to any one or more ways ofdoing it, and I only show the sleeve'method in the drawingsforillustration and as an example of one of the simplest methods.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a quilting-machine,the combinati0n,with three or more parallelneedle-bars connected by a series of bolts, 1), of sets of sleeves B, ofdifferent lengths,adapted to be slipped on said bolts, whereby thespaces between the bars may be varied.
